Wrenchers We have a 100 kW roof mount system where we are going to need to use snow guards in the array. We are in the northeast (ground snow loads of 40 psf at the site). Pitch is about 4:12. I was looking at the Snow Dog by Alpine SnowGuards <https://alpinesnowguards.com/roof-type/solar-panels/snow-dog-blk>. The one thing that struck me is the wording*:*
*"there may be times and conditions where snow accumulates to depths greater than 6”. If this happens, it is the responsibility of the building owner to clear the excess accumulation. This will ensure structural integrity of the solar array racking system and the building structure." * Getting 6" is common here (or at least it used to be), and in no reality will the building owner clear snow off their array after a storm. I'm wondering what you all do for snow guards. My engineer would make sure the building structure could handle the additional loads caused by slowing the shedding of the snow, but should I be concerned about the integrity of the racking and also of the frames of the solar panels? Is there another product worth looking into? Thanks for any thoughts.
